RAWHIDE-WOUND GUN;

SPECIFICATION forming part of Letters Patent o. 521,911, dated June 26, 1894;

Application filed July 29. 1893. Serial No. 481,844' (No model.)

.To a/ZZ whom. t Imay concern.-

Be it known that I, FREDERICK LATULIP, a citizen of the United States, residing at Syracuse, in the eount'y` of Onondaga and State of New York, have invented certain new and useful Improvements in Guns; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention, such as will enableoth'ers skilled in the art to which Io it appertains to make and use the same.

My invention relates to improvements in the construction of guns, more particularly 1o the class known as built up guns; and it consists in surrounding a specially constructed core, properly bored, by a casing of rawhide iuclosed by a shell of metal or a jacket of steel wire, as will be hereinafter more fully explained and specificallyset forth in the claims. f -f zo The principal objects of the invention are to cheapen and lighten the construction .of guns and gun-barrels, and, at the same time, to so strengthen the same that they will`withstand the explosive strain of not only the z5 usual charge but an unusual one. These objects I accomplish by the means illustrated in the accompanying drawings, in which- Figure l represents a vertical longitudinal sectional View of my improved gun; Fig. 2,

3o asimilar view showinga modification thereof; Fig. 3, a vertical transverse section taken on line o; fo, of Figi; Fig. ha vertical longitudidinal section of a section of the gun,shewing the overlapping layers of rawhide, and Fig.

5, a vertical longitudinal section of a gunbarrel of my improved construction.

Referring to the drawingsz--1`he letter A indicates a core of steel or other suitable metal, properly bored, and provided with ex- 4o terior collars or bands a arrang d 'at intervals thereon. These collars orbands are cast integral with the core and serve to prevent endwise movement of the rawhide casing during firing. rl`l1e breech portionof the core is provided with a series of step-like depressions tt, the purpose of which will be presently made apparent.

Ali indicates a casing of rawhide surrounding the core, and before being applied is o treated as follows, vizz-I take the ordinary #Jied commercial rawhides and soak in water sufiiciently to soften the/hides andremove the lime therefrom. 'The hides are then Well fleshed and split into thin layers in any Well Aknown manner. These layers are then soaked in a bath of liquid ammonia for from ten to" fifteen minutes, after which they are thoroughly dried and cut into strips desired for winding. A The strips are then subjected to a bath consisting of a solutionof sulphuric acid and Water, in about the proportion of one part of acid to thirty'two of water, for about ten minutes. A bath of pui-e naphtha might be substituted for the sulphurie acid one above mentioned with equally good results. The effect of either of these baths is to cause a drawing or exudationvof the oil er grease contained in the rawhide strips. The yresultof this treatment leaves the strips, when dried, hard and tough like horn, and possessing great strength.

of the width.

[n winding the stripsaround the core, cement is first applied to the succcssive'overlapping and this application of the cement also serves to soften the rawhide suficiently to permit of easy and perfect Winding; and in winding the spaces or seats between the collars or bands are first filled. The strips are wound tightly around the core between said points in spiral overlapping layers until the spaces 0I' seats are filled flush with the tops of the collars 4or bands, the cement pressure and strain causing the layers to adhere firmly. After the spaces or seats have been filled with the rawhide layers the breech is then wound in alike manner. In winding the breech I commence at the outer end and wind the strip` both surfaces to cause layers to adhere,

around the core, filling the first step or de- Y pression, and, when filled even with the seeoml step or depression, the winding is centintdd until both of said steps or depressions I are filled flush with the third step or depression, and so tht winding continues until the breech is incaset flush with top ofthe first collar or banda. After allot the spaces or seats and depressions are filled with the spirally wound overlapping layers of rawhide the winding is continued the entire length of the gun until the required thickness is obtained, after which the gun is plaeedin a suitablelathe and the rawhide casing is turned down to the in Fig. 3.

5 what I claim as new,

desired shape. When turned down to the required shape a steel cap, C, having a groove or rabbet c, is fitted tightly over the breech portion of the thus far constructed gun, and a steel shell D, conforming to the taper of the forward portion of the gun is forced over the rawhide until its inner end fits snugly within the groove or rabbet c of the cap, where they are secured together. The cap C is provided with the usual trunnions, as shown Inplace of the shell D I may provide the rawhide casing with a wire jacket, E, and instead of making the core-breech solid, as shown in Fig. l, I may make it with a screwthreaded opening closed by a screwtlireaded breech-block, as shown in Fig. 2.

In constructing gun-barrels, as shown in Fig. 5, I provide t e core with the collars or bands asin the larger gun, and wind the rawhide strips around the said core in the same manner, filling 4the spaces or seats first, and then continuing the winding until the desired thickness is reached. After being turned down a shell, F, is forced over the rawhide casing until its inner end abuts against the abutment G, to which it is brazed or soldered.

By constructing lguns and gun-barrels as hereinbefore described the tendency to transverseand longitudinal rixpture is reduced to a minimum, as the rawhide gives the necessary tension of the charge.

Having thus fully described my invent/imi, and desire to secure by Letters Patent, is

with integral to withstand the explosive strain 1. A gun having a metallic core provided with retaining collars or bands, an intermediate casing of rawhide and a metallic cover# 1 ing for said casing.

a metallic coreformed 2. A gun having I bands on its exterior,

collars or and having an intermediate casing formed of strips of raw hide wound in successive overlapping layers, and a metallic covering for said casing.

3. In a gun the combination with ametallic core having a series of retaining collars or bands formed on its exterior and along its length, the same being of less diameter than the gun when built up, of an intermediate casing formed of strips of raw hide wound upon said core and between and over said collars or bands, and an exterior metallic covering, substantially as described.

4.. The combination with' a steel core having retaining bands or collars formed on its peripl1ery,of an intermediate coveringformed of strips ot' raw hide wound in layers thereon and between said collars, said layers or stri ps being subjected to a softening bath ot cement, whereby they are rendered flexible in winding aud'heldin position when wound,

xsubstantially as and for the purposes specified.

In testimony whereof I affix my signature in the presence of two witnesses.
